Preferably, the identification area is arranged in the center of the well lid body.

Preferably, the character signboard is provided with a corresponding character mark.

Preferably, the character signboard and the arrow signboard are respectively fixed at the bottom of the central groove and the bottom of the peripheral groove by using viscose glue. .

Preferably, the character signboard and the arrow signboard are respectively fixed at the bottom of the central groove and the bottom of the peripheral groove by screws.

Preferably, the periphery of the character signboard and the arrow signboard is respectively provided with a clamping block which is protruded outwards and corresponds to a clamping groove arranged in the central groove and the peripheral groove, the clamping block is inclined downwards, and the clamping block has certain flexibility.

Preferably, the character signboard and the arrow signboard are made of stainless steel.

Preferably, the circumferential groove communicates with the exterior of the logo area through the groove.

Compared with the prior art, the beneficial effects are that: 1. the arrow sign board of the utility model can indicate the access direction of the access pipeline of the inspection well and the direction of water flow; 2. the arrow sign and the character sign are convenient to install; 3. the character signboard and the arrow signboard are positioned in the groove, and a moving object on the well cover is difficult to directly contact the character signboard and the arrow signboard, so that the character signboard and the arrow signboard are well protected.

Detailed Description

The invention will now be further described with reference to the accompanying drawings, in which reference is made to fig. 1-4, illustrating specific embodiments.

A manhole cover comprises a manhole cover body 1 and an identification area 2. The center of the identification area 2 is provided with a central groove 21, a character signboard 22 is arranged in the central groove 21, and the character signboard 22 is provided with a character signboard 221 'rain' or 'dirty' of a corresponding inspection well type. Peripheral grooves 23 which are not less than the number of pipelines connected into the inspection well are arranged around the central groove 21, and arrow signs 24 with directional arrows 241 are arranged in the peripheral grooves 23 corresponding to the positions and directions of the pipelines. According to the water flow direction of the pipeline, the arrow direction on the arrow mark plate 24 is arranged to point from the outer side to the center of the mark area 2 or from the center of the mark area 2 to the outer side, and is consistent with the water flow direction of the pipeline. The character signboard 22 and the arrow signboard 24 are positioned in the grooves 21 and 23, and moving objects on the well cover are difficult to directly contact the character signboard 22 and the arrow signboard 24, so that the character signboard 22 and the arrow signboard 24 are well protected.

The identification area 2 is arranged in the center of the well lid body 1.

The letter signboard 22 and the arrow signboard 24 may be fixed to the bottoms of the central groove 21 and the peripheral groove 23 by glue or screws, respectively.

Another fixing manner of the character signboard 22 and the arrow signboard 24 is that the peripheries of the character signboard 22 and the arrow signboard 24 are respectively provided with a latch 222, 242 protruding outward corresponding to the latch grooves 211, 231 provided in the central groove 21 and the peripheral groove 23, the latch 222, 242 is inclined downward, and the latch 222, 242 has a certain flexibility. The character signboard 22 and the arrow signboard 24 are respectively placed in the central groove 21 and the peripheral groove 23, the clamping blocks 222 and 242 correspond to the clamping grooves 211 and 231, the clamping blocks 222 and 242 are knocked by a tool, the clamping blocks 222 and 242 are made to extend into the clamping grooves 211 and 231, and then the clamping blocks are changed from being inclined to be horizontal, so that the signboard 22 and 24 is difficult to separate from the grooves 21 and 23 even if the signboard 22 and 24 is subjected to the action force of an animal moving on the well cover. The signboard 22, 24 can be disassembled, and when the signboard 22, 24 is lifted up by a tool, the fixture blocks 222, 242 will be inclined downwards to be separated from the fixture grooves 211, 231, which is convenient for replacement.

The character signboard 22 and the arrow signboard 24 are made of stainless steel.

The peripheral groove 23 is communicated with the outside of the identification area 2 through the groove 243, so that residual water in the peripheral groove 23 can flow out of the peripheral groove 23 through the groove 243, and the identification plate 24 is prevented from rusting.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
